The same rule applies, if the Zelle was sent to his business account under the LLC then you fill out the 1099-NEC to the business name.
Either way you entered it, you can still take the deduction as contract labor expense. It will matter more on their end how it was filed.
Going forward, make sure to have every contractor fill out a W9 Form before they begin work. This way they can enter the correct name and Tax ID number they prefer. And you will have all the info necessary to file the 1099-NEC after the year ends.
